integral of 7x+4

Solution

\int 7 x + 4 d x

Solution

\frac{7 x ^{2}}{2} + 4 x + C

Solution steps

\int 7 x + 4 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 7 x d x + \int 4 d x

\int 7 x d x = \frac{7 x ^{2}}{2}

\int 4 d x = 4 x

= \frac{7 x ^{2}}{2} + 4 x

Add a constant to the solution

= \frac{7 x ^{2}}{2} + 4 x + C
